What is the difference between <button> and <input> in PHP?

In PHP, <button> and <input> are both used to create form elements, but they have different functionalities. The <button> element is typically used to create a clickable button that can contain text, images, or other HTML elements. On the other hand, the <input> element is used to create form controls like text fields, checkboxes, radio buttons, and submit buttons. When using <button> in PHP, you need to specify the type attribute as "submit" to make it function as a submit button.

&lt;form action=&quot;submit.php&quot; method=&quot;post&quot;&gt;
  &lt;button type=&quot;submit&quot; name=&quot;submit_button&quot;&gt;Submit&lt;/button&gt;
&lt;/form&gt;
